GAGE F OR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 463,641, dated November24, 1891.

Application filed February 16,1891. Serial No. 381,635. on model.

To all whom it may concern:

Be it known that LWILLIAM E. NORRIS, of Middleborough, in. the county ofPlymouth, State of Massachusetts, have invented certain new and usefulImprovements in Gages for Printing-Presses, of which the following isadescription sufficiently full,clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being bad to the accompanying drawings,forming part of this specification, in which-- Figure 1 is a perspectiveView showing a printing-press tympan with my improved gages in positionfor use; Fig. 2, an inside plan of a portion of the tympan-cover,showing the method of attaching the gage; Fig. 3, an edge elevation ofthe same; Fig. 4, an edge elevation of the gage detached, and Fig. 5 atop plan view.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates, especially, to a de-' tachable paper-gage forprinting-presses; and it consistsin certain novel features hereinafterfully set forth and claimed, the object being to producea simpler,cheaper, and more effective device of this character than is now inordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation:

In the drawings,"A represents the tympan of an ordinary handprinting-press, on which the cloth or facing of card-board b is securedby metallic clamps d in the usual manner. It is a general custom tocement a slug or similar device to said facing to gage the position ofthe paper on the tympan. The position of such gage frequently has to bechanged, tearing the facing b when removed and necessitating thesubstitution of a new facing. In my improvement this and otherobjections are overcome.

My improved gage 0 consists of two members h 2'. The member it has itsupper face beveled, as best shown in Fig. 4, one of said members beingreduced to a thin point at and the opposite end provided with a verticallip or flange it, from which a stud m (see Fig. 5) projectslongitudinally of said member. The member 2' is adapted to rest on theinclined upper face of the member j, one'end thereof being socketed toreceive the stud m, and its opposite end being provided with a verticalflange, forming a head 10, against which the paper on the tympan restswhen in use. Said member t'is slotted longitudinally, at q, and aset-screw r passes through said slot into the member h, whereby saidmembets are adj ustably secured together; or instead of said set-screw ascrew-stud t may be secured to the member h and project through saidslot, a nut 12 being turned onto said screw to bind the memberstogether, as best shown in Figs. 3 and 4.

In the use of my improvement the cutting-' pointj of the member hisforced through the outer sheet of the facing b, as shown in Fig. 2, withthe head 19 of said member toward the top of the tympan. By turning onthe nut o the member 2' is clamped securely against said facing. Thestud m on the member It serves to center the membert' and preventaccidental lateral movement thereof after the gages are placed. The slotq in-the member 1; permits longitudinal adjustment after attaching-thegage to the facing 12.

It is frequently desirable to employ a gage at the sides of the tympan.When thus used, the edge of thefacing is inserted between the membersand clamped without penetrating said facing by the point j.

Having thus explained my invention, what I claim is The gage 0,comprising the member h, having the reduced portion j, flange k, andstud m, in combination with the member 2', slotted at q and providedwith the head 19, and mechanism for adj ustably securing said memberstogether, substantially as described.
